“What we’re trying to do right now is to have a set of standards, a set of criteria, and have a decision-making process that will govern our counterterrorism actions — we’re talking about direct action, lethal action — so that irrespective of the venue where they’re taking place, we have a high confidence that they’re being done for the right reasons in the right way,” [John] Brennan said in a lengthy interview at the end of August.

A burly 25-year CIA veteran with a stern public demeanor, Brennan is the principal architect of a policy that has transformed counterterrorism from a conventional fight centered in Afghanistan to a high-tech global effort to track down and eliminate perceived enemies one by one.
